' CAR-AXLE .BEA RlN C L-f SPECIFICATION forming part of- Letters Patent No. 605,827, dated June 14, 1898. Application filed January 17,1898. Serial No. 666,854 (No model.)

To all whom it may concern:

Be it known that I, FRANK E. NULsEN, acitizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Bearings for Oar-Axle Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to certain new and useful improvements in bearings for car-axle boxes, and it has particular reference to the manner of securing the bearing between the key and the brass.

The primary object of this invention is to provide an effective means for holding a bearing in place between the key and the brass without its being rigidly connected to either; and-a further object of the invention is to provide a construction which will permit of the arrangement of the bearing within the key, after which the bearing is permanently" secured in place.

With the'seand other ends in view my invention consists in the peculiar construction and arrangement of parts hereinafter described,and shown in the accompanying drawings, in which Figure 1 is a longitudinalsectional view of a car-axle box embodying my invention. Fig. 2 is a bottom plan View of the key. Fig. 3 is a detail'sectional view showing the fastening pin as it appears before being riveted upon the fastening-plate. Fig.4 is a similar view showing the fastening-plate held in position by the pin. Fig. '5'is also a detail sectional View showing the fastening-plate provided with the pin.

Referring to the drawings, in which like letters of reference denote corresponding parts in allthe figures, A designates a journal-box of any ordinary construction adapted to receive the axle B.

I My inventio'n may be embodied with any.

I 5 means of the key'D and the bearing E. The

key is of substantially the usual form, consisting of a Hat plate provided with a circular recess F to receive the bearing. The walls of the recess are provided with an inwardly-extending annular flange G, which flange'is open at oneside or provided with an open section H. The flange may be open at other points, but I have found that it is sufficient to provide one opening in the flange, as illustrated in Fig; 2. 1 The bearing is provided with outwardly-extending lips I, which project into the space between the flange Grand the back of 'the key when the bearing is arranged in position in the circular recess in the key.

In order to secure the bearing in place in the key, I provide a plate J, adapted to fit in the opening H in the flange and be secured to the key by means of a fastening device, preferably in theform of a pin or projection or lug K. This fastening device K may be formed integral with the key in the manner shownin Fig. 3 and riveted down upon the plate, as shown in Fig. 4, or the device may be made integral with the plate and riveted down upon the key, as shown in Fig. 5. r. In assembling the different parts of my invention one lip on the bearing is arranged between the flange and the back of the key by inserting it through the opening H in the flange, and it is then turned around until the other lip comes to its position at the opening in the flange, whereupon itis slipped into place and the bearing turned so that the lips will not register with the'opening. The fastening-plate J is then secured in place to fill the opening and form a continuation of the fiange. The plate is provided with an opening to receive the pin K, after which the pin is riveted down upon the'plate, as shown in Fig. 4:, or if the pin is made integral with the plate the key is provided with an opening to receive the pin, which is then riveted down upon the key, as shown in Fig. 5.

While the invention may be practiced with a single opening in the flange, more than one opening may be provided, if de"sired,[and I IOG more than one pin may be employed or-the I pin may be horizontally arranged instead of vertically, and various other modifications maybe made, which will occur to those skilled in the art, without departing from the invention.

By securing the bearing in the key in the manner hereinbefore described I secure a free movement of the bearing Within the limits of the recess in the key, as the bearing and key are looselybut permanently secured together.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. 111 a car-axle box, the combination with a key having an inwardly-extending flange provided with an opening, of a bearing provided with lips and adapted to be held in the key by said flange, a plate for closing the opening in the flange, and means for securing said plate to the key, substantially as described.

2. In a car-axle box, the combination with a key having an inwardly-extending flange provided with an opening, of a bearing provided with lips and adapted to be held in the key by said flange, a plate for closing the opening in the flange and a pin adapted to secure the plate to the key to close the opening in the flange, substantially as described.

3. In a car-axle box, the combination with a key having an inwardly-extending flange provided with an opening, of a bearing provided with lips and adapted to be held in the key by said flange, a plate for closing the opening in the flange, a pin formed integral with the key and adapted to receive the plate and be riveted thereon to secure the plate to the key and close the opening in the flange, substantially as described.
